That). Further, in the case of a relatively large number of people, a large propane gas cylinder used daily in a general household is used to supply a fuel gas to a large gas stove or a plurality of gas stoves (hereinafter referred to as Conventional Example 2).

[0003]

[Problems to be solved by the device]

 Since the above-mentioned Conventional Example 1 is intended for a case where a small number of people use a relatively small amount of fuel gas, it is easy to carry and carry, but it has weak fire power and cannot be used for a large gas stove. On the other hand, when using a large household propane gas cylinder as in Conventional Example 2, a strong fire power can be obtained, but on the other hand, the cylinder itself is designed to be safe against high pressure and robust enough to withstand repeated use over many years. Since it is a remarkably heavy pressure container, it is not easy to carry and carry, and it cannot be easily obtained like a disposable gas cylinder. The present invention has been made in consideration of such circumstances, and is a fuel gas supply device that can be easily obtained, can be easily used for outdoor cooking, can generate strong fire power, and can be easily carried and carried. To provide. Moreover, it is a technical issue to provide easy handling and to provide the fuel supply system at a low cost by relaxing the strict standards for safety and endurance of a fuel gas cylinder for home use.

【Example】

 The present invention will be described in detail below with reference to the drawings. FIG. 1 is a perspective view of a portable fuel gas supply device according to the present invention, in which a main part is broken away, FIG. 2 is a perspective view illustrating the arrangement of a gas cylinder in a carrying case, and FIG. 3 is a vertical cross-sectional view of FIG. 4 and 5 are external perspective views of the carrying case.

This portable fuel gas supply device includes a portable case 3 for accommodating a plurality of disposable gas cylinders 1 containing a fuel gas, a case opening / closing lid 2 that constitutes a cylinder pressing means 21, and is arranged inside the portable case 3. , Each nozzle connection port 4 corresponding to the nozzle 14 of each disposable gas cylinder 1, a check valve 5 connected to each nozzle connection port 4, a communication pipe 6 that connects the check valves 5 in parallel, and a communication pipe 6 It is composed of a gas pressure regulator 8 and an opening / closing valve 7 which are connected to each other through a gas supply port 9 of the opening / closing valve 7 exposed to the outside of the carrying case 3.

The carrying case 3 is formed into a substantially equilateral triangle as viewed from the front, and is partitioned into a cylinder storage chamber 3a and a piping chamber 3b by a partition wall 13 shown in FIG. 1. The cylinder storage chamber 3a has six disposable gas cylinders. 1 is accommodated in three horizontal stages, and a check valve 5, a communication pipe 6, a gas pressure regulator 8 and an opening / closing valve 7 connected to each nozzle connection port 4 are connected and connected to the piping chamber 3b, and a portable case is provided. The gas supply port 9 of the open / close valve 7 is exposed to the outside of 3.

A plurality of cylinder guide plates 18 are horizontally provided in the cylinder storage chamber 3 a. By loading the fuel gas cylinders 1 along the cylinder guide plates 18, each cylinder 1 is guided by the guide plate 13. The cylinder nozzle 14 which is held at a fixed position and fixed to the partition wall 13 is configured to be accurately fitted into the connection port 4.

The case opening / closing lid 2 is hinged to the lower portion of the cylinder insertion opening of the carrying case 3 with a hinge 11, and the normally closing valve (not shown) of the cylinder nozzle 14 of each cylinder 1 has a total closing valve urging force. Against this, the case opening / closing lid 2 is closed and locked by the lock mechanism 10. The case opening / closing lid 2 of the portable case 3 and the opening / closing lid locking mechanism 10 constitute a cylinder pressing means 21. In addition, in order to open a large number of cylinder nozzles 14 all at once, a fairly strong lid closing force is usually required. However, in this embodiment, many cylinders 1 are arranged on the lower stage side near the hinge 11, Due to the principle of "lever", the case opening / closing lid 2 can be easily closed without requiring a strong closing force.

A protrusion 17 is additionally provided near the connection port 4 of the partition wall 13. When the cylinder 1 is pushed along the cylinder guide plate 18, the cylinder 1 is slightly rotated to allow the protrusion 17 to move. Is engaged with the notch 16 of the head ring 15 of the cylinder 1 to prevent the cylinder 1 from rotating and to maintain the direction of the cylinder 1 in the correct rotational position.

A check valve 5 is connected to each of the nozzle connection ports 4, and each check valve 5 is connected in parallel to one gas pressure regulator 8 via a communication pipe 6, and the pressure regulator 8 is connected to the gas pressure regulator 8 in parallel. Is connected to a gas supply port 9 via an opening / closing valve 7. As a result, the fuel gas is discharged from the plurality of disposable gas cylinders 1 housed in the carrying case 3 in parallel via the nozzle connection ports 4, the check valve 5, the communication pipe 6, the gas pressure regulator 8 and the opening / closing valve 7. You can take it out. As a result, compared with the case of using a full-scale large propane gas cylinder, the fire power is comparable, and the disposable gas cylinder 1 itself is easy to obtain and easy to carry and carry. In the drawings, reference numeral 7a is an opening / closing operation handle of the opening / closing valve 7, 12 is a handle for carrying the carrying case 3, 19 is a leg of the carrying case 3, and 20 is a ventilation hole.

A large number of the ventilation holes 20 are formed on the slopes on the left and right of the carrying case 3, and when the use of gas such as cooking is started and the six cylinders 1 start to release gas all at once, the liquefied gas is discharged. This is for alleviating the temperature drop because the temperature of the cylinder 1 is rapidly reduced by vaporization and the gas release amount is insufficient when the temperature is too low. That is, by providing a large number of ventilation holes 20 in the portable case 3 to promote ventilation, the temperature of the cylinder 1 is prevented from dropping sharply. It is desirable that the cylinder guide plate 18 also be provided with a ventilation hole (not shown). Further, it is desirable that legs 19 are provided on the bottom surface so that the bottom surface of the case is separated from the ground so that the bottom surface of the case 3 can also ventilate. Further, it is advisable to appropriately provide ventilation holes (not shown) in the partition wall 13 that separates the cylinder storage chamber 3a and the piping chamber 3b.

In the above embodiment, the case in which the carrying case 3 has a triangular shape has been illustrated, but the present invention is not limited to this. Further, in the above embodiment, the case opening / closing lid 2 is exemplified as a cylinder pressing means for pressing each of the disposable gas cylinders 1 in the cylinder valve opening direction to open the normally closed valve of the nozzle 14. Other cylinder pressing means may be attached to each of the cylinders 1, and other appropriate modifications can be made.

[Effect of the device]

 In the present invention, since the fuel gas is taken out in parallel from the plurality of disposable gas cylinders housed in the carrying case, the following effects can be obtained. I. Compared to the case of using a full-scale large flammable gas container, the heat power is comparable, and the container itself is lightweight, making it easy to carry and carry. B. Also, a check valve is provided at each cylinder connection port, and individual cylinders can be replaced, facilitating handling. C. Moreover, since the container is a small-sized disposable gas cylinder, the fuel supply device as a whole can lighten the strict standards regarding safety and endurance, which are similar to those of household fuel gas cylinders, and can provide them at low cost. D. When the cylinder pressing means is composed of the opening / closing lid of the carrying case and the opening / closing lid locking mechanism, the opening / closing lid can be closed and collectively locked with a weak force.
